As a reliable method of assessing the structural integrity of pile foundations (and deep foundations), we provide Sonic echo / Impulse response pile integrity testing (PIT) in accordance to ASTM D5882-16 and AS 2159-2009 methodology.This testing method may alternatively be referred to as “Low-strain dynamic pile test”.
Structural Auditing QA/QC
Based on stress wave propagation and reflection theory; a stress wave (compression / tension) in a uniform rod is reflected if the wave encounters an impedance change or discontinuity. Structurally sound shafts made with concrete should have:
The characterization and location of defects is only as good as the accuracy of wave velocity determination and quality of the pile. Results may be categorized into:
